Road trips are special. Unless you're living in your vehicle, road trips will provide extraordinary moments, thoughts, views and visions, which don't always come in daily lives at home base.
It's important to bring writing utensils and journals. Handwriting gives us special insights on our own personal inner journey. I also think its fun to bring a book, a sketch pad, cards (maybe tarot cards to read up on and get the whole camp interested in the path ahead).
When you get back home, it's fun to match pictures and sketches, swatches, flowers you pressed, people you've written about to the pages of your journal.
